Why this park works

Seeley Greenbelt works because its connectivity score (61) is above average and its enclosure (67) is also above-average (18 transit stops sit within a 400 m walk; 17 intersections fall within 100 m of the edge).

What limits this park

Most distinctive characteristic

Most distinctive feature: exceptionally high connectivity (61, top quartile).

Jacobs reading

Seeley Greenbelt sits between an urban social park and an ecological retreat — moderately useful for both, exceptionally suited to neither.

Tradeoffs

The park is enclosed by buildings (67) but the surrounding streets are quiet (edge activation 0) — frame without animation.

Typology classification

Ravine / Naturalized Parkalso reads as Neighbourhood Park

Classified as Ravine / Naturalized Park: 99% ravine overlap, 1% canopy. Secondary read: Neighbourhood Park (2.6 ha, framed by 9 mid-rise vs 0 towers).

Edge Activation

25% weightpartial 60%

0.0 / 100

Within 100 m of the park edge: 0 active uses (none) and 2 dead/hostile uses (parking_lot). Active edges keep "eyes on the park" through the day; parking lots, blank institutional walls, rail and highway frontages drain street life.

68 buildings within 25 m of the park edge (9 mid-rise, 59 low-rise, 0 tower); avg edge height 6.4 m (~2 floors); 6.2 buildings per 100 m of 1,099 m perimeter — strong frontage density; edges are low-rise (mostly 2–3 floors); no towers immediately adjacent. "Eyes on the park" come strongest from the 9 mid-rise edge buildings.

Border-vacuum factors within 50 m of the park: parking_lot, parking_lot. Jacobs warned that highways, rail, parking lots and blank institutional edges act as "vacuums" — they suppress foot traffic and isolate the park from its neighbourhood.

Does this score feel accurate?

Your read of Seeley Greenbeltmatters. We’re testing whether the model lines up with how people actually use the park. Submissions are stored locally; no account needed.

Tell us how this park feels

We measure structure (canopy, edges, connectivity). You measure feeling. Both matter — and disagreement is itself useful civic data.

What would improve this park?

Generated from the weakest measured dimensions — a starting point, not a prescription.

Activate the edges: encourage cafés, retail or community uses on the streets that face the park; replace blank or parking-lot edges where possible.
Diversify what people can do in the park — playground, washroom, water, shade, performance, sport, garden — even small additions raise this score.
Increase canopy and reduce paved area. Shade and water features extend usable hours and seasons.
